Application mea Marelfieio'.' serial No. 551,359.

To all whom 'it may concern:

Be it known that I, WILLIAM C. GoLnlmm,M

a citizen of the United States, residing at Wichita, in the county ofSedgwick and State of Kansas, have invented new and useful Improvementsin Bracket-Lamps, of which the following is a specification.

The present invention relates to lamps,

and more particularly that type in which liquid fuel or illuminant isvaporized and mixed with air before burning.

The primary object is to provide a bracket structure of a simple, noveland effective character.

In the drawings :-Figure 1 is a side elevation of the lamp, with theglobe and globe support illustrated in section. Fig. 2 is a detailsectional view on an enlarged scale through the vaporizer, air mixingmeans and burner.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment disclosed, a horizontal vaporizing tube 3 is employed,having at one end a suitable supporting shell 4, by means of which saidtube can be mounted on a wall or other support. The other end of thetube is provided with a head 5, from which depends a vapor dischargenozzle 6. A valve casing 7, disposed in line with the tube, hasrotatably mounted therein, a valve stem 8 that passes through a packinggland 9, andhas an exposed knurled head 10. This stem carries at itsinner end a suitablevalve 11 Vthat operates against the direction offlow of vapor, and is movable into and out of coaction with a valve seatl2 that is thus interposed between the vaporizing tube and the nozzle.

A collar 13 is fitted upon the outer end portion of the vaporizing tube,and carries an upstanding stem 14 and a depending stem 15. Theupstanding stem 14 supports a suitable bell 15a. Ahead 16 is providedwith an outstanding iinger 17 having an opening 18, through which thestem 15 passes, and a set screw 19, threaded into the end of the linger17, has its inner end engaging in a groove or socket 20 formed in thestem 15, so that the said head 16 is supported by the stem. This headhas in its upper side, an opening 21 that detachably receives the nozzle6, and it is furthermore provided with an outstanding tube extension 22forming an air inlet.

The outer end of said tube extension supports an adjustable airregulating cap 23.

The head 16 furthermore carries a depend ing air and vapor conductingtube 24, that extends through the top and nearly to the bottom of an airand vapor mixing chamber.

25 carried by said tube. This chamber 25 is provided with one or moredepending burners 26 having perforated caps 27, and constituting mantlesupports.

In this structure, the liquid illuminant passing through the tube 3,will be vaporized by the heat from the burner, and will dischargethrough the nozzle 6, into the tube 24. Air will be entrained throughthe extension 22, and the air and vapor will consequently pass into themixing chamber 25, from whence it will discharge at the burners 27,where it will be burned. The mantles supported from these burners, willconsequently be made incandescent. The said mantles are preferablyinclosed in a suitable globe 28 that is carried by a supporting ring orsleeve 29. This sleeve is mounted on the set screw 19 and the extension22.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a lamp, the combination with a substantially horizontal vaporizingtube, of means located at one end for supporting the same, a dependingnozzle carried by the other end, a substantially horizontal valvecontrolling the passage of vapor from the tube to the nozzle, and havinga handle at one end of the tube, a straight air and vapor tube directlyabove the burner, and having In testimony whereof, I have hereiinto setdepending and upstanding stems in line my hand, in the presence of twosubscribing therewith, means carried by the upper end witnesses.

of the air and vapor conducting tube for de- VILLIAM C. COLEMAN. 5tachably supporting the same from the de- Witnesses: Y
